This application for patent is a division of Patent No. 824,797, dated July 3, 1906.

I attain the objects of my invention by the mechanism illustrated in the accompanying drawings, in which,

Figure 1 is a sectionalview of a hub taken on the lines 11 of Fig. 2. Fig. 2 is an end view partly in section taken on the lines 22 of Fig. 1.

In both of the views like parts are designated by the same reference characters. V a ,In carrying out my invention I provide a hub 1, having a cylindrical bearing surface 2 and a flange 3. Surrounding the hub is a flanged collar 4 and between this collar and the flange are secured the spokes 5, by

means of bolts 6. Between the bearing surface 2 and K the spindle 7 is a bushing or sleeve 8. This cylindrical .bushing 8 is free to rotate upon the spindle 7 and within the hub 1. The inner surface of the bushing is provided with two or more spiral oil passages 9 and its outer surface is provided with similar passages 10. The passages on the' inside of the bushing are arranged in the opposite direction from those on the outside, that is to say, if the passage 9 is a right hand passage,then the passage 10 on the outside will be a left hand one, cansing the passage to be of opposite twist;

A ring 11 of fiber is arranged on the inner end of the hub and bears on a shoulder 12 formed "thereon. Engaged withthe ring 11 is a second ring 13 of fiber,-which bears against the inclined portion 14 of the axle shoulder 15.' The ring 13 is of less depth than the ring 11.

' Outside of the ring 13 is a ring 16 of felt or similar maj a shoulder portion 21adjacent to the shoulder 17 at the end of the spindle. Between thes'e"- two portions'is a" washer 22 of any suitable material. The end cap 19 is prevented from accidental turning by means of a cotter 23. -The end cap is screwed up until it pinches the washer 22. The circular face portion 20 will then engage with the end of the hub and force the latterin- Serial No. 266,545.

ward. This action will compress the washers 11 and 13 and the latterengaging with the curved portion 14 of the enlargement 15 on the axlewill be expanded, compressing the felt washer 16'between it and the hub,

thereby producing an efiicient dust excluding device and aineans for preventingthe escape of oil. The degree of compression of the felt washer 16 can be determined by the thickness of the washer 22, a greater or lesser thickness of the latter being employed as required. g Y

The'cap 19 is provided with wings 241 which with the .barrel and the flange of the cap constitute oil chambers 25. An oil passage 26 in each chamber serves as a means of communication between the space between the axle and the hub and the outside of the cap.

A cylindrical dust cap 27, having a hexagonalpor tion 28 for attachment of a wrench and the threaded portion 29,- engages with threads 30, formed upon the hub l. The joint between the dust cap and the hub is oil tight, so that the dust cap may constitute a reservoir for lubricant. Comm nication between the reservoirs and bearing {surfaces is made through the oil passages26. Suitable means is provided for preventing accidental rotation of the cap 27, an approved .means being disclosed in my Patent No. 824,797, previously referred to. i

In order 'to get the best results from the bearing surfaces, the spindle hub and bushing should be of differ ent material and the thickness of the bushing should bear a determined relation to the frictionalcharacter- 1 of the .materials. If, as an instance, 'as I haye found in practice, the hub be made of m'alleable iron and the spindle of steel, the bushing made of bronze and softer than the spindle or hub, and the half diameter of the spindlebeing seven eighths of an inch and the half diameter of the central bore of the hub being one and oneeighth inches, leaving a separating space of one-quarter of an inch and the bushing of sufiicient thickness 'to make a close fit, and the parts being properly lubricated the surface betweenthe hub and bushing and between the bushing and spindle will each have the same frictional characteristics, that isto say, the friction will .the space between the, spindle and the hubl The cap 27 being mounted upon the hub will rotate therewith causing the il to be circulatedaroun'd the wings of the cap 24', kee ing all of the chambers supplied with lubricant. The bushing being in constant rotation with the wheelthe oil will be moved through one of the spiral passages 9 or 10 into the bushing in one direction and return in the other direction, passing out through the surrounding the same, and a hub surrounding the bushing lowermost oil passage 26 into thedust cap 27. i It be noted that the bushing is free to move longitudinally upon the spindle to a limited extent bit it cannot pass and 'tree to turn thereon, the spindle, hub and bushing being of diflerent materials and the thickness of the bushing being so proportioned that the surfaces between the hub and bushing'andbetween the bushing and spindle will have the same. frictional, characteristics, 'whereby the i one end of the spindle there being 011 passages communicatlindrical bushing mounted thereon and free to turn, the

beyond the confines of the cap 19 and the ring 11.

Having now'described my invention what I claim and desire to secure by Letters Patent, is;

1. The combination with awlindrical spindle, of; a cylindrlcal bushingmounted thereon and tree to' turn, the

bushing willrotate at less speed than the hub.

4. Thecombination with a cylindrical spindle, ot a loose cylindrical bushing'shorter than the'spindle and surrounding the same, and tree totui'xi and move longitudinally thereon, and a hub surrounding the bushing and tree to said bushing h ving spiral grooves, a hub mounted on the 11:11 thereon, the i hub and bushing being of i bushing and free to turn thereon, and anoil reservoir'ating with the reservoir, the bushing being shorter than the spindle and'free to move longitudinally thereon. 2. The -c0mbina'tion'with a cylindrical spindle, of a cysaid bushing having spiral grooves, a hubmounted upon ent materials and the thickness or the bushing being so proportioned that the surfaces between the hub and bushing and between the bushing-and spindle will have the same frictional characteristics, whereby the bushing will rotate at less speed than the hub, and will be free to .move longitudinally on the spindle.
